Selective Image Layer Synthesis for Wireless Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, such as Wi-Fi, face issues with privacy infringement when sharing images or information between source and sink devices, as all image layers are transmitted, including those not intended for sharing, leading to unintended display on both devices.
Innovation Solution
A method and apparatus for selective image distribution, where a source device configures and synthesizes image layers to differentiate between display and non-display layers, generating a share image that excludes non-display items, which is then transmitted to a sink device, ensuring only intended information is shared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all image layers are transmitted from source device to sink device, then complete image information is shared, but user privacy is infringed due to unintended information being displayed
Solution Approach 1:
The image is divided into multiple layers, where each layer represents a different component or element of the image. This segmentation allows selective transmission of only certain layers (e.g., background layers) while excluding others (e.g., overlay layers containing sensitive information), thus resolving the contradiction between complete information sharing and privacy protection.
Solution Approach 2:
The patent extracts and identifies specific layers within the image that contain non-displayable or sensitive information. By taking out these particular layers from the transmission set, the system shares complete visual information while excluding privacy-sensitive content, directly addressing the harmful effect of unintended information display.
2Object-affected harmful factors
If selective image layers are transmitted to protect privacy, then user privacy is protected, but image information completeness is reduced
Solution Approach 1:
Different layers of the image are assigned different quality attributes based on their sensitivity and display requirements. Background layers are marked as transmittable while overlay layers containing sensitive information are marked as non-transmittable. This local differentiation allows the system to maintain overall image completeness while protecting specific privacy-sensitive regions.
3Object-affected harmful factors
If the source device transmits only display image layers, then privacy is protected, but the complexity of layer configuration and synthesis increases
Solution Approach 1:
The source device performs preliminary analysis and classification of image layers before transmission. By pre-identifying which layers contain sensitive information and should be excluded, the system avoids the need for complex real-time processing at the sink device, thereby managing complexity while maintaining privacy protection.
Solution Approach 2:
The patent introduces an intermediary processing mechanism that automatically analyzes image layers, identifies sensitive content, and determines which layers should be transmitted. This intermediary layer handles the complexity of layer configuration and synthesis, shielding the user from direct interaction with complex technical processes while ensuring privacy protection.

AI summary
A method for selective image distribution using a processor includes determining whether an image includes a non-display image layer and a display image layer; and generating, using the processor, a share image by synthesizing the display image layer. A device includes a layer configuring unit to determine whether an image includes a non-display image layer and a display image layer, and a layer synthesizing unit to synthesize the display image layer to generate a share image.
